We have some targeted Blind SQL Injection focusing on some randoms URLs, and all the time the same three parameters. We have actually make a list of different IP addresses, all located in China (hn.kd.ny.adsl), and more particular from the Henan province. All theses source IP addresses generating 30 distinct events. The 22/04/2010 events are not related with this Use Case.

When starting the Blind SQL Injection scan, the source port stay static during 26 of 30 events and the last 4 events are have also a static source port, but different from the initial 26 events. We have also seen that some source IP only test doing 10 events, all these teen events with the same static source port.
